SOURCE: control panel looks ok but dryer wont start

Sounds like an electronic problem on the timer circuit board.

SOURCE: My dryer keeps saying Lint

try two things. first, run it empty without the lint filter installed. if it gives you the same error message, install the filter, but disconnect the flexible duct connected to the back of the dryer. try it again. if it still wont work, you will have to get it serviced and cleaned out. if it works with the ducting removed from the back, your dryer duct is clogged up. check your yellow pages for dryer duct cleaning. The lint filter error message is just your machines way of saying it is not getting enough air flow. It can be caused by a clogged duct also.

SOURCE: my siemens electric dryer will not start a cycle.

One is a thermal limiter that operates the heating element and the other is a moisture sensor.

Check to see that the door switch is operating properly with an ohmmeter (with the power disconnected, of course).

SOURCE: I want a Siemens manual my dryer won't start

Below is a ''copy and paste'' of an answer I gave someone else:
If it is a gas dryer, there are two (round black colored) solenoid switches that control the gas flow. They go bad frequently, (and even more frequently when you buy cheap Chinese replacements). Replacing them is _very_ easy, and there is no danger of releasing gas while replacing them. (''Gas Control Solenoids''). The ''click'' you hear is the thermostat ''calling for'' the solenoids to turn on... the actual ''click'' is the ''igniter'' that would ignite the gas which is supplied by those solenoids. // Note: This problem usually shows itself with the dryer repeatedly re-igniting the gas during drying (i.e. ''lots of that ''clicking'' noise). Then, finally the solenoids die altogether and it never ignites even once. // In my opinion, this is the most common GAS dryer repair, and the easiest to repair. Each solenoid ''slides'' onto a post, and is removed the same way. // WARNING: the solenoid posts are a part of the ''GAS VALVE''. DO NOT remove any screws from the ''GAS VALVE''. ONLY remove the screw(s) on the bracket _above_ the solenoids (which is holding them in place). Once the ''hold-down'' bracket screws (sometimes just a ''hold-down'' screw... no ''bracket'' per say) are removed, the solenoids will pull right off of the posts, and replaced the same way. Just make sure you position them the same way; (i.e. ''make sure the connector for the wires are facing the same way as original''). // Ps... The full retail cost of a set of two is about $20 bucks, and as little as $5 bucks for the cheap Chinese replacements. Note: These _cannot_ ''leak'' gas. They work magnetically. They either work or they don't, but they do NOT ''leak gas'', including during removal. Just don't remove screws from the ''gas valve'' as I explained above.

Ultrasense dryer sending lint filter red light, E01 message and it is beeping after starting to dry.

Try unplugging for a _full_ 24 hours. If problem still exists, bad computer board.

(I feel like I should copy this answer to a notepad and paste it every time I see these questions. This is why I avoid computerized appliances like the plague. Owning such appliances is _truly_ worth having extended warranties).

My maytag electric dryer won't start the light flashes off then on again

Remove exhaust. clean out lint. Remove back cover. Clean lint out of entire air system. Likely air block or overheating. If not, check back bottom of dryer for a white and black plastic thermal fuse. Unplug the 2 blue wires and electrical tape them together to bypass. Test dryer. If it works, replace thermal fuse before operating.

My siemens electric dryer will not start a cycle. The lint filter light is on, but dryer will not start. All ducting is clear. Is there a sensor that could have gone bad? I see two on bottom of lint...

One is a thermal limiter that operates the heating element and the other is a moisture sensor.

Check to see that the door switch is operating properly with an ohmmeter (with the power disconnected, of course).

Bosch Dryer misfunction

Check the fuse. This is a German unit, so every part including the light bulb is 208/240 volts. If the fuse for the dryer on the back is open the unit will not start.
